ReferenceDiagnosis
H. H. Dijkstra and R. N. Kilburn 2001Shell fragile, height to ca. 5 mm, orbicular, equivalve, equilateral, anterior auricle slightly larger than posterior, umbonal angle ca. 120°. Prodissoconch height ca. 200 μm. Both valves sculptured with minute antimarginal radial striae and 14–20 fine, irregularly spaced, scaly radial lirae, plus fine regularly spaced, somewhat crenulated, commarginal growth lines; scales often damaged. External sculpture visible from the interior. Auricles continuous with disc and similarly sculptured. Anterior auricle of RV separated from disc by distinct suture, with 4–5 radial ridges and concentric lamellae, the latter strongly developed at dorsal margin. Hinge line straight. Byssal fasciole and notch well developed. Active ctenolium with 2–3 teeth. Resilifer triangular. Valves transparent white, sometimes with white dots.
